Revealing mistake: While Monica and Rachel are talking about Chandler's "jollies to Jaws" Rachel's wearing a colorful flowery top, and after Joey walks in just as Monica takes her seat at the table in the closeup, it's Jennifer Aniston's stand-in, wearing a blue top, who is seated beside Monica. And Rachel's hair is waivy in the flowered top, but straight in the blue top. (Viewed in widescreen).
Visible crew/equipment: In the scene where Prue comes home and finds Andy inside the manor. There is a shot where if you look behind Andy's shoulder you can see half of the body of the director in the background in the observatory room sitting in a director's chair. (00:16:00)
Continuity mistake: When Ryan is lighting Marissa's cigarette with his, at the start of the shot it's full, then the shot goes to Ryan and it's still full. But then the shot goes to Marissa and if you look at Ryan's cigarette you can see it is almost all gone. Then the shot goes to Ryan and the cigarette is full again. (00:09:00)
Continuity mistake: When Izzie is looking at the patient board, there are some lines on it which have been wiped out. But in the next scene we actually see Meredith walk to the board and wipe these exact same lines off (even though they were previously rubbed out...) (00:34:05)
Continuity mistake: During the wedding, there are flashes of the different people from throughout the story. In the one showing Lady Catherine and her daughter, in the first shot, Anne can be seen sitting very close to the arm of the sofa, but in the zoom out, she is further along.
Continuity mistake: When Buckingham is about to be arrested, the camera is looking directly at him. At this angle, his black fur collar is flipped up, covering the neck of his white shirt. When the scene changes to a wide shot behind him, the collar is folded down. (00:35:00 - 00:35:50)
Visible crew/equipment: When Jackie tells Eric that she can really use a friend right now, in the next shot facing Eric just as he says, "Okay, well, good luck with that," the camera and crew member wearing a blue shirt can be seen at the left side of the screen. (00:01:00)
Continuity mistake: Tara is sitting at her desk and tells Max they will have sex the following night, and she teases him that she "Might even bring some props." Right as she says this line, the camera cuts. In the first shot, she has one pencil in each hand, but in the second shot, suddenly both pencils are in her left hand. The position of her hands changes between cuts as well.
Continuity mistake: Episode 1 - When the commissioner kisses his wife at the beginning of the first episode, he is holding the holstered gun in his left hand and his ID in the right hand. That's in the first shot, because his daughter enters the room bringing coffee, and now the two items swapped hand. (00:05:10)
Continuity mistake: At the diner when Tsunoda and Retsuko are talking, Tsunoda pulls out a red phone with a white heart on it from her purse. In the close up she is pulling it out with her left hand and the phone is horizontal with the heart on its side. It then cuts to a wide angle and suddenly she's holding the phone upright with both hands.
Continuity mistake: Episode 2x15, "Witness for the Execution": When David and Maddie are debating whether or not to help Lawrence Everett, the towel David uses to wipe shaving cream off his face jumps around during the scene. It's around his neck, then in his hands, then on his shoulder, and back in his hands, etc. (00:15:40)
